This pull request refactors the test suite to use the Pest testing framework instead of PHPUnit, resulting in more concise and modern test files. The main changes include removing the abstract BaseCommandTest class, converting test classes to Pest's function-based syntax, and moving setup logic into beforeEach() hooks. This improves test readability and maintainability.

Test suite modernization and migration to Pest:

• Removed the abstract BaseCommandTest class, as Pest handles shared setup via beforeEach() hooks instead of inheritance. (Tests/Command/BaseCommandTest.php)
• Converted command test classes (ConsumerCommandTest, DynamicConsumerCommandTest, MultipleConsumerCommandTest, PurgeCommandTest) from PHPUnit to Pest, replacing class-based tests and setUp() with beforeEach() and Pest's function-based test() syntax. (Tests/Command/ConsumerCommandTest.php, Tests/Command/DynamicConsumerCommandTest.php, Tests/Command/MultipleConsumerCommandTest.php, Tests/Command/PurgeCommandTest.php) [1] [2] [3] [4]
• Updated event test files (AfterProcessingMessageEventTest, BeforeProcessingMessageEventTest, OnIdleEventTest) to Pest syntax, removing class wrappers and using test() functions for clarity and brevity. (Tests/Event/AfterProcessingMessageEventTest.php, Tests/Event/BeforeProcessingMessageEventTest.php, Tests/Event/OnIdleEventTest.php) [1] [2] [3]
